E27 prop questions

[SV_Ariel]

Thanks for everyone’s help. I did redo my reduction. Down to 2.6 to 1 and that greatly increased the acceleration without touching the prop. I am still going to change to a three blade this winter.

Elgyn- I am using two Power Queen 25.6V 100ah, LifePO4 batteries. I can’t remember what I paid for them but I think it was somewhere around $1000 for both. My boat is on a mooring so I barely use the motor. We typically sail off the mooring then use the motor a little bit coming in. I’ve never had the batteries below 90% yet so I can’t speak to any battery lifespan.

I did switch the drive over to belt drive as well. The chain was only temporary until I figured out what final drive I needed. It is incredibly quiet now.

Hi Elgyn, I've got two banks of LiFepo4 batteries. One at 160ah and another at 40ah. I like having two banks - backup if one has issues. 400ah should get you motoring for days ;-)
